An intermediate lemma of the split of OpenAI's proof of OAI.CriticalSK.critical_mixing_bounds, carved from OpenAI's openai/math development for this platform. The statement and its proof are OpenAI's (OpenAI, Critical mixing in the Sherrington-Kirkpatrick model (result family 227), OpenAI Math Release, September 25, 2026, result family 227, github.com/openai/math, Apache License 2.0), ported to Lean 4.33.1 and Mathlib 0df444a.

The statement, as published (namespace OAI.SKGap, with open Matrix Real Set MeasureTheory ProbabilityTheory Filter, open scoped BigOperators Matrix.Norms.Frobenius SchwartzMap Topology):

lemma generalTemplateGaussian_centered_continuous_s2 [Nonempty ι] (f : 𝓢(ℝ,ℂ)) {R j A D : ℝ}
    (hR : 0 ≤ R) (hj : 0 ≤ j) (hA : 0 ≤ A) (hD : 0 ≤ D) (F : List (WordTemplateLetter m)) (r : ℝ)
    (g : EuclideanSpace ℝ (MatrixCoordinates ι)) :
    Continuous (fun θ : WordParameter m ι=>matrixCentered
      (fun x : EuclideanSpace ℝ (MatrixCoordinates ι)=>generalTemplateMatrix f R hR j A D F θ (goeMatrix r x)) g)

Definitions. The statement is written with OAI.SKGap.MatrixCoordinates, OAI.SKGap.WordParameter, OAI.SKGap.WordTemplateLetter, OAI.SKGap.generalTemplateMatrix, OAI.SKGap.goeMatrix and OAI.SKGap.matrixCentered (definitions bundle OAIQ072A000 of this split).
